ARE THE BIG BANKS COLLABORATING TO BANKRUPT FOSSIL FUEL COMPANIES?

This article raises a number of questions. Do the big banks have the will and the desire to do this? Do they actually have the power, given that there are many well-financed banks not under their control, such as Chinese banks? Why would oil and gas companies spend $billions on exploration and refineries if they could be bankrupted and how could they fund this now unless they can self-finance? 

Why would Mark Carney make such claims if they are simply nonsense? Surely they would turn him into a laughing-stock.
